Specification of Letters Patent.

Patented Feb. 5, 1907.

To (LZ/, whom, it 17m/y concern:

Be it known that I, ABEL SACK, residing at Ashton, in the county of Sherman and State of Nebraska, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a specification.

My invention relates to certain new and useful improvements in mechanical movements, and it particularly seeks to provide an improved crank-slide motion for all kinds of machinery.

In its generic nature my invention comprises a supporting framework having grooved guideways, a shaft mounted in said frame and projecting through said guideways and carrying friction-rollers to coperate with the guideways, means for moving the shaft along the guideways and simultaneously rotating the same, together with me ans for transmitting` the motion of the shaft.

In its more detailed nature my invention comprises certain novel constructions, combinations, and arrangements of parts, all of which will be first described in detail and then be specifically pointed out in the appended claims, reference being had to the accoinp anying drawings, in which- Figure l is a perspective view of my invention. Fig. 2 is a front elevation thereof, the supporting-frame being broken away in part to more clearly illustrate the invention. Fig. 3 is a side elevation of a modified form of my invention. Fig. 4 is a perspective view of a y F 1g. 5 1s a modified form of my invention. front elevation thereof, showing the position of the parts when the shaft is at the limit of its movement in one direction in the guideways in full lines and showing the position of the parts when the shaft is at the limit of its movement in the opposite direction in dotted lines.

Referring now to the accompanying drawings, in which like numerals and letters of reference indicate like parts in all of the 'ligures, it will be seen that l designates a supporting-frame, which comprises the side bars l@L l, having the elongated slots lb Ilb to serve as guideways, which will be hereinafter again referred to. The side bars la are connected by transverse beams l, as shown.

2 designates a crank-shaft passing through the supports l1L and the guideways therein and having its ends 2"L reduced in diameter to receive friction-rollers 3, which operate in the guideways, and on the end of the shaft 2 are crank-disks 4, having wrist-pins 4, which connect with the bearing 5a of pitmen or levers 5, which are pivotally secured at 5b to the supporting-bars la, as shown. The shaft 2 is also provided with a crank 2b, disposed midway the side bars l, which crank connects with the piston-rod 6 through a divided bearing 6@L on the end of the piston-rod, and the piston-rod 6 may be provided with a piston 7 to operate in the cylinder 8secured to one of the cross-bars 1 of the supportingframe.

Adjacent one of the side bars 1a the shaft 2 carries a ily-wheel 9, which is `fixedly secured thereto by a set-screw or key 9a, so that it will turn with the shaft.

l() designates a rod which projects through a bearing-aperture 1f in one of the transverse bars 1C and has an enlarged portion 10a to cooperate with the aperture in the transverse bar. One end of the rod l0 has a divided bearing 10b to receive the shaft 2, the shaft 2 being of a slightly reduced diameter, as at 2X, to receive said bearing.

In the operation of my invention the bar 10 may be secured to any suitable source of reciprocating power which will transmit its reciprocation to the shaft 2, making it move from end to end in the slideways 1b, and by virtue of the fixed levers or pitmen that are connected with the shaft andthe supportingframe the shaft will be rotated and the movement of the shaft imparted to the piston-rod, which causes the piston in the cylinder' to operate. rI`he cylinder 8 may be provided with a valved o'lftake-pipe 8, if desired, so that the saine can be used as an air-compressor, it being noticed that the stroke of the piston-rod when power is applied to the rod l() will be double that of the rod l0.

Instead of using the piston as an air-compressor the same may be used as an engine and the power transmitted through the medium of the rod, being simply a reversal of the operation just above described.

i In Fig. Li I have shown a modified form of my invention, in which the crank-disks 4 have their crank-pins provided with rollers IOO 1l and the arms 5 are omitted. To take the place of the arms 5, I provide bracket mem-- bers l2, which may be detachably secured to the supporting-bars la of the framework to coperate with the rollers ll and produces the same result as when the arms 5 are used.

While I have described two methods of using my invention, particularly by using the piston as an air-compressor or as an engine, as the case may be, yet I desire it understood that my invention can be used in connection with any machinery with which it may be found to be applicable.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the complete construction, 0peration, and numerous advantages of my invention will be readily understood by those skilled in the art to which the invention appertains, and I desire to call attention to the fact that my invention can be Vused with the supporting-framework held in a vertical plane, in a horizontal plane, or inclined at any angle desired.

l/Vhen the invention is used with the parts in a vertical plane, as shown in Fig. l, then the weight in the fly-wheel on the downward movement of the shaft-piston will add its equivalent power to that exerted by the piston, and hence aid thepumping stroke thereof when the device is used as an air-compressor or other pump.
